    The foundation has no vapor barrier underneath, making it wet. I doubt this is off gassing. So is it browning or mildew?

    How would you fix this? IMG_0498.JPG

      I think I might try this before I attempt to HWE with the browning treatment. Where can I get some before this sunday? I live about an hour north of Jondon and TCS

      Honestly, I've never had a problem that I can remember of removing coffee or urine stains. I've always used peroxide to handle it.

      Will my Acid rinse, undiluted, be just as good? Or do you think I should get some Browning treatment or remover at TCS this weekend?

      There are several types of browning treatments or browning removers. They are not all the same.
      Some are based on sodium bilsulfite or sodium metabilsulfite which are reducing agents. Others are acids. Similar to your acid rinse but at different strengths and probably added surfactants to help them penetrate the fibers better. Some are peroxides or oxidizers. Be sure you know which you are using, espcially if you intend to try multiple products on the same area.

      Try to determine if it is mold. If you hit mold with a rotary or Cimex or OP or even a vacuum, there will be mold spores everywhere and that can come back to be a big rpoblem for you later.

      Rick's suggesting of encapsulation with peroxide is a good one. We might disagree on the specific product to sue.

      Larry's suggestion of testing a few approaches and then going with the one that works makes a lot of sense, especially because you are not certain on the cause of the stain.

      I don't want to use a chemical that would lock the stain in, so what order would you use the different treatments to help prevent that?

      Have you tried testing a small area with your acid rinse and a white rag?

      There should be any issues as long as you don't use an oxidizer and a reducer together. An acid can reduce the effectiveness of an oxidizer. Just rinse between products and you should be fine.

      If you test each in a different small area, there should not be much mixing of different products. You will find out what works.
      Personally, I would start with encap / O2 as that is the easiest for me to do over the size you are delaing with and the equipment I have.

      If it's mold would a moisture detector sense it? If it's wet shouldn't it be treated as mold anyway?

      I would think treat it and dry it then come back and clean as normal or use a post treatment on all the carpet.

      I just tested 2 spots with my usr, and didn't see much. But that was just a 5minute test. When I go this Sunday to clean it, I'll check those spots and see how it came out with that dwell time

      What do the bottom of the mats look like?

      What are the chances that commercial carpet as late as that appears to be contained cellulose as a component?

      Is that an after pic?

      That is before I'm going to try my best tomorrow. Can you dumb it down "appears to be contained cellulose as a component" ?

      This carpet is probably at a minimum 15years old. I've been cleaning for this company for around 12 years

      I seriously doubt that it's cellulose browning, even considering the age of the carpet.

      I'm with Rick and Scott that you should encapsulate it with a formula that contains peroxide. In the very unlikely chance that it is browning, oxidizers are useful for that as well.

      I wouldn't use an acid treatment and reducing in any sequence, by the way. That may cause the release of some fairly irritating fumes.

      Thanks for chiming in Jim. I plan on encapping with a grey pad and bonnet with the peroxide formula like you said first, but what should be my second attempt if this doesn't fix it?

      Based on my experience with this problem, I don't expect that you will be able to make this as good as new, or even significantly better.

      I would expect that your efforts will "lessen the intensity" of the staining. (How is that for a non commital weasel word phrase?)

      When synthetic fibers become stained in this fashion under these circumstances , they rarely respond with impressive results.

      You can try misting it with a strong peroxide stain remover, but I doubt it will do much more.

      Did y'all notice how he refrained from saying my CSR suggestion was stupid?

      Since I'll be focusing on the browning from the high alkaline in the moisture and or the mildew, how will your encap HydrOx treat it? What properties does it have to remove the browning?
